Application June 23, 1954, Serial No. 438,664

2 Claims. (Cl. 24-230) This invention relates to a remotely controllablequick release device particularly adapted for use in log binders toprovide emergency release in the event if circumstances renderingmanipulation of the conventional binder hazardous.

It is therefore among the primary objects of the invention to provide anovel, simple, effective and efficient release means acting as anauxiliary connection in the usual binder assembly.

Another object of the invention is to provide a binder release which maybe actuated from a remote position so as to preclude injury to theoperator as a consequence of a sudden release of the bound logs.

Another object is to provide a quick release device operable by a simpleunidirectional motion to permit release of the binding strain andsubsequent operation of the conventional binder mechanism withoutsubjecting the operator to the danger of unexpected release of the load.

The novel features that are considered characteristic of the inventionare set forth with particularity in the appended claims. The inventionitself, however, both as to its organization and its method ofoperation, together with additional objects and advantages thereof, willbest be understood from the following description of a specificembodiment when read in connection with the accompanying drawing,wherein like reference characters indicate like parts through theseveral figures and in which:

Figure 1 shows our new and improved binder release in holding positionwithin a binding cable or chain;

Figure 2 is a side view of the release, taken on line 2-2 of Figure 1;

Figure 3 is a side view, taken on line 3-3 of Figure 2, partially brokenaway for convenience of illustration;

Figure 4 is a fragmentary view illustrating how the release isaccomplished, and

Figure 5 is a side view of the release, taken on line 5-5 of Figure 2.

Referring to Figure l of the drawings the bound logs are indicated bynumeral 1, a conventional binding cable 2 and the chain 3 connectedtogether by suitable means such as a Well known binding mechanismindicated at 4 adapted to stretch the cable and chain tightly around thelogs by the action of the lever 5. The chain 3 is secured to the loadbinder mechanism 4 in the usual manner by way of the chain passingthrough a ring 6, which in turn is part of the swivel connection 7 ofthe binder. The chain is held to the desired adjustment by the usual U-shaped lock 8, which embraces one of the links of the chain and over thetop of the ring 6. Usually the end 9 of the cable 2 connects directlywith the link 10 of the load binder 4.

The present binder release is indicated by the letter R and it includesa body 11 comprising two side walls 12 and 13, spaced apart andconnected together by integral webs 14 and 15. A lever 16 is pivotallymounted between the said side walls 12 and 13 upon a pin 17 and isprovided at one end with a cam 18 formed adjacent the pivot pin 17.

An eye bolt 19 having a shoulder 20 is adapted to engage under thetransverse web 14, as at 21, while its opposite end is connected to theend 9 of the cable 2 by way of the eye portion 22. The shoulder 20 ofthe bolt 19 is held under the transverse web 14 by the action of the tip23 of the cam 18 when the lever 16 is in the position shown in Figures1, 2, 3 and 5. This lever is held in this position by the spring loadedball 24 engaging the socket 25 of the lever 16, as best illustrated inFigure 3.

The ball 24 is biased by a spring 26 and the tension of the spring 26can be varied by the threaded plug 27 to the proper tension of the ball24 within the socket 25. A pull cord 28 is secured to the end 29 of thesaid lever 16 by way of the hole 30. Bars 31 form part of the'body 11and extend downwardly, having a cross pin 32 passing therethroughadapted to connect to the link 33, which in turn connects to the swivel10 of the load binder. This is best illustrated in Figures 1, 2 and 3.In use the cable 2 of the binding assembly is connected to the bolt 19of the present quick release unit by way of theeye 22. The main body 11of the unit is connected to the load binder unit 4 by the link 33passing over the pin 32 and between the cars 31. The load binder 4 ispermanently connected to the chain 3. When the binding unit is placedaround the logs, the bolt 19 is passed down between the cam 23 of thelever 16, as illustrated in Figure 4, after which the lever 16 isbrought to the position shown in Figures 1, 2, 3 and 5. The ball 24registering with the socket 25 holding the lever in this position,causing the tip 23 of the cam 18 to bear against the side of the bolt19, holding the shoulder 20 under the web 14 at 21.

The chain 3 is then roughly adjusted within the ring 6 while the loadbinder is in its released position. The lever 5 is then brought down tothe position shown, tightening the binding chain 3 and cable 2 aroundthe logs. When it is desired to release the binder unit from around thelogs, the operator stands quite some distance from the load and pullsthe pull cord 28, which pulls the lever 16 to the position shown inFigure 4, allowing the bolt 19 to disengage itself from the body member11. This is done by the tip of the cam 23 moving to the position shownin Fig. 4, allowing the shoulder 20 of the bolt to release itself fromunder the cross member 14. A slight slope to the shoulder and to the web14 allows the shoulder to release easily. When the bolt 19 is releasedas above described, the whole binding unit, including the cable 2, chain3, binder 4 and our quick release falls to the ground in a singleconnected unit so that the same can be quickly and easily applied inanother binding operation.

Although a certain specific embodiment of the invention has been shownand described, it is obvious that many modifications thereof arepossible. The invention, therefore, is not to be restricted except in sofar as is necessitated by the prior art and by the spirit of theappended claims.
